    Abstract: A membrane-integrated hydration reactor that is operable to produce an associated alcohol product from an olefin using water includes a solid acid olefin hydration catalyst in a production zone and a hydrophilic membrane operable to selectively permit pervaporation of water one-way and not permit pervaporation of the associated alcohol or permeation of the olefin at olefin hydration process conditions in a separations zone. The production zone is operable to form a production zone product mixture made of the associated alcohol and any unreacted water. The associated separations zone is operable to form and produce both the associated alcohol product and a pervaporated water product from the production zone product mixture. A method of olefin hydration for forming an associated alcohol product from an olefin using water uses the membrane-integrated hydration reactor at olefin hydration process conditions.

    Abstract: The present disclosure relates to an apparatus and process for forming medical devices from an injectable composition. The apparatus includes a supply assembly configured to maintain and selective dispense a first precursor and a second precursor, a mixing assembly configured to mix the first and second precursors, and at least one catalyzing element including a transition metal ion to aid in the polymerization of the first and second precursors. The process includes dispensing a volume of the first precursor and a volume of the second precursor into a mixing assembly and mixing the first and second precursors. The first and second precursors each possess a core and at least one functional group known to have click reactivity with each other. The mixed precursors are contacted with a transition metal catalyst to produce a flowable composition for use as a medical device.

    Abstract: A catalytic static mixing reactor has a conduit casing defined about an axis of a fluid flow. A catalyst is deposited on a mixing element. The mixing element is adapted to be inserted in the conduit. The element provides an exceptionally high surface area and is formed to obstacle the primary flow inducing a first order mixing phenomenon. The element is formed with at least one irregular surface or edge capable of inducing a second order mixing phenomenon. The irregular surface is adapted as a catalytic supporting surface. The supporting surface supports the deposition of the catalyst thereon so that a third order chemical reaction phenomenon is coupled with that of said first and second order mixing phenomenon at the catalytic surface so that a reactant to be converted in the fluid flow is converted to at least one predetermined product during said first and second order mixing phenomenon.

    Abstract: Surface-active solid-phase catalyst activity may be substantially improved by creating deliberate repetitive surface-to-surface contact between portions of the active surfaces of catalyst objects. While they are immersed in reactant material such contact between portions of the active surfaces of catalyst objects can substantially activate the surfaces of many heterogeneous catalysts. Examples are given of such action employing a multitude of predetermined shapes, supported catalyst structures, etc. agitated or otherwise brought into contact to produce numerous surface collisions. One embodiment employs a gear pump mechanism with catalytically active-surfaced gear teeth to create the repetitive transient contacting action during pumping of a flow of reactant. The invention is applicable to many other forms for creating transient catalytic surface contacting action. Optionally catalytic output of such systems may be significantly further improved by employing radiant energy or vibration.
